Le Mans will now have to have a percentage of laps under pure electric power
I know what you are referring to but I think that requirement was dropped. It was something proposed by the ACO/FIA and then I believe with the new regulations coming in the manufacturers didn't want this extra expense on top of all the millions they are spending already. It required rapid charging systems, and massive changes to the way the powertrain worked. I could be wrong but I think it was put on the back burner or it's still being discussed. I think LMP1-H may go the way of the new F1 regs and the hybrid systems will be simplified not made more complex.
I have mixed opinions. Hybrid is the future for sure but my concern in motorsport use is the cost. You go from a relatively simple petrol engine to a complex petrol/electric setup that can cost up to five times the amount to run during the year.
In LMP1-H the millions that went into trying to out-perform one another on the powerplant side of things has effectively killed the class off. The factory teams were developing whole new cars and powerplants every year that were wildly different to the year before.
Touring car has always been the lower end of the budget scale (apart from in the factory super touring days) but once you start involving factory teams and hi-tech like hybrid the costs will spiral like you wouldn't believe and my fear is this will kill privateers or simply kill the class completely.
There's a reason why TCR is popular. It's cheap(ish), the cars are available off the shelf, and anyone can run a team if they have the budget and desire. Just like GT3, GT4.
I'm not disagreeing with you, I'm just putting my view across. In my view Hybrid, electric, hydrogen fuel, etc. belongs in sports car racing not in touring car.
Anyway back to the main story, glad that a merger has been agreed, looking forward to 2018.
